AZEOTROPIC DATA FOR BINARY MIXTURES
J. Gmehling, J. Menke, J. Krafczyk, K. Fischer, J.-C. Fontaine, and H. V. Kehiaian
Binary homogeneous (single-phase) liquid mixtures having an
extremum (maximum or minimum) vapor pressure P at constant
temperature T, as a function of composition, are called azeotropic
mixtures, or simply azeotropes. The composition is usually
expressed as mole fractions, where x1 for component 1 in the liquid phase and y1 for component 1 in the vapor phase are identical.
Mixtures that do not show a maximum or minimum are called
zeotropic. A maximum (minimum) of the P(x1) or P(y1) curves
corresponds to a minimum (maximum) of the boiling temperature T at constant P, plotted as a function of x1 or y1 [see T(x1) and
T(y1) curves, Types I and III, in Fig. 1]. Azeotropes in which the
pressure is a maximum (temperature is a minimum) are often
called positive azeotropes, while pressure-minimum (temperature-maximum) azeotropes are called negative azeotropes. The
coordinates of an azeotropic point are the azeotropic temperature
TAz, pressure PAz, and the vapor-phase composition y1,Az , which is
the same as the liquid-phase composition x1,Az.
In the two-phase liquid-liquid region of partially miscible (heterogeneous) mixtures, the vapor pressure at constant T (or the
boiling temperature at constant P) is independent of the global
composition x1 of the two coexisting liquid phases between the
equilibrium compositions x1′and x1′′ (x1′ < x1′′).
The constant vapor pressure (boiling temperature) above the
two-phase region of certain partially miscible mixtures is usually
larger (smaller) than the vapor pressure (boiling temperature) at
any other liquid-phase composition in the homogeneous region.
In this case, the vapor-phase composition is inside the miscibility
gap. Mixtures of this type are called heteroazeotropic mixtures, or
simply heteroazeotropes. (Fig. 1, Type II), as opposed to the other
types of azeotropes, called homoazeotropes.
Only in a few cases partially miscible mixtures present a positive or negative azeotropic point in the single-phase region, outside the miscibility gap, similar to the azeotropic points of
homogeneous mixtures (Fig. 1, Types IV and VI).
A few binary mixtures, for example the system perfluorobenzene + benzene, may present two azeotropic points at constant
temperature (pressure), a positive and a negative one. They are
called double azeotropic mixtures, or simply double azeotropes.
(Fig. 1, Type V).
The knowledge of the occurrence of azeotropic points in binary
and higher systems is of special importance for the design of distillation processes. The number of theoretical stages of a distillation column required for the separation depends on the
separation factor α12, i.e., the ratio of the Ki-factors (Ki = yi/xi) of
the components i (i = 1, 2). The required separation factor can be
calculated with the following simplified relation (Reference 1):
�12 = K1/K2 = (y1/x1)/ (y2/x2) = (�1P1s)/ (�2P2 s)
(1)
where �i is the activity coefficient of component i in the liquid
phase and Pis is the vapor pressure of the pure component i.
In distillation processes, only the difference between the separation factor and unity (�12 – 1) can be exploited for the separation. If the separation factor is close to unity, a large number of
theoretical stages is required for the separation. If the binary system to be separated shows an azeotropic point (�12 = 1), the sepa6-210
ration is impossible by ordinary distillation, even with an
infinitely large number of stages.
Following eq. (1) azeotropic behavior will always occur in
homogeneous binary systems when the vapor pressure ratio P1s/
P2s is equal to the ratio of the activity coefficients γ2/γ1.
Various thermodynamic methods based on gE-models (Wilson,
NRTL, UNIQUAC) or group contribution methods (UNIFAC,
modified UNIFAC, ASOG, PSRK) can be used for either calculating or predicting the required activity coefficients for the components under given conditions of temperature and composition
(Reference 2).
Because of the importance of azeotropic data for the design of
distillation processes, compilations have been available in book
form for quite some time (References 3-7). The most recent
printed data collection was published in 1994 (Reference 8). A
revised and extended version appeared in 2004 (Reference 9).
A collection of approximately 47,400 zeotropic and azeotropic
data sets, compiled from 6600 references, are stored in a comprehensive computerized data bank (Reference 10). The references
from the above-mentioned compilations and from the vapor-liquid equilibrium part of the Dortmund Data Bank (Reference 11)
were supplemented by references found from CAS online
searches, private communications, data from industry, etc.. Over
24,000 zeotropic data and over 20,000 azeotropic data are available for binary systems. Nearly 90% of the binary azeotropic data
show a pressure maximum. In most cases (ca. 90%) these are
homogeneous azeotropes, and in approximately 7–8% of the cases
heterogeneous azeotropes are reported. Less than 10% of the data
stored show a pressure minimum. Approximately 21,000 of the
data sets stored were published after 1970.
The table below provides information about azeotropes for 808
selected binary systems. Compounds are listed in the modified
Hill order, with carbon-containing compounds following those
compounds not containing carbon. In columns 1 and 2 are the
molecular formulas of components 1 and 2 written in the Hill
convention. In column 3 the names of the components are given,
either a systematic IUPAC name or a name in ubiquitous use.
Columns 4, 5, and 6 contain the azeotropic coordinates of the
mixtures: temperature TAz, pressure PAz, and vapor-phase composition y1,Az . The explanation of the type of azeotrope (column 7) is
given by the following codes:
O: homogeneous azeotrope in a completely miscible system
L: homogeneous azeotrope in a partially miscible system
E: heterogeneous azeotrope
X: pressure maximum
N: pressure minimum
D: double azeotrope
C: system contains a supercritical compound
